Proactivity and pinning in the non-reciprocal XY model with vision anisotropy
Gabriele Bandini, Asja Jelic, Andrea Gambassi
We study a non-reciprocal XY model on a square lattice, in which spins interact with their nearest neighbors through vision-induced anisotropic interaction. Such anisotropy breaks…

The XY model with vision cone: non-reciprocal vs. reciprocal interactions
Gabriele Bandini, Davide Venturelli, Sarah A. M. Loos +2
We study the behavior of the classical XY model on a two-dimensional square lattice, with interactions occurring within a vision cone of each spin. Via Monte Carlo simulations, we…
